Configuration Bits

The configuration bits can be programmed (read as '0')

or left unprogrammed (read as '1') to select various

device configurations. These bits are mapped in

program memory location 2007h.

Address 2007h is beyond the user program memory

space and it belongs to the special test/configuration

memory space (2000h - 3FFFh). This space can only

be accessed during programming.

To find out how to program the PIC16C84, refer to

tion (DS30189).
